If you read through it, they mention the manual for your motherboard:________________________________________________________Well, the manual for the DVD266u-RN on the web site is the one that
comes with the actual motherboard.. BUT.. I took a look at the manual
for the DVD266-R. Granted, not the same board, but I thought it would
be worth a try.

The manual for the DVD266-R is just one page with some information and
pictures.. not much, but surprisingly helpful. The pin layout is
different from the one listed in my own motherboard's manual, so I gave
it a try. You can take a look at the manual here
(http://www.iwillusa.com/support/manual/dvd266_r.pdf)________________________________________________________

I even translated a page from Korean with a link to the same PDF but got the same 404 error.So I don't think the manual is out there to be downloaded, and the fact that the company's website was hacked would answer your question about the Error message, but you could read through the page at forums.2cpu.com and see if what they are discussing pertains to your problem at all.

I have provided a link for you to copy and paste into your web browser to go to the Gigabyte model GA-5SMM support page.

The page shows a list of manual downloads for your motherboard, click on 3rd download on the list from America, after opening and go to page 3-4 for jumper settings for your model mainboard.I recommend printing pages you my need for future reference.
